CSRmesh™ FAQs

Since CSR launched CSRmesh™ a year ago, I have met with people from the world over who are all interested in learning more about it. As more and more developers look to bring easy to use and attractive IoT and smart home products to market, it means more and more questions about the solution head my way. I thought it would be useful to list the queries I hear most often about CSRmesh and answer them here in this post. If the responses here don’t answer some of the questions you have about CSRmesh, don’t hesitate to post in the comments, refer to the wiki or post in the CSR Support forum – one of the team will get back to you. We’ll also post a version of these FAQs on the CSRmesh development kit product page and keep it regularly updated.

FAQ

 

  • Has mesh been standardized by the Bluetooth SIG?

Not yet, but the Bluetooth SIG is working towards standardization. On February 24th 2015, the SIG issued a press release announcing the formation of the Bluetooth® Smart Mesh Working Group, which is dedicated towards building the architecture that will make mesh networking a standard capability on Bluetooth Smart technology. CSR’s own Head of Global Standards, Robin Heydon, is chairing the Working Group and leading the charge. CSR cannot comment on when standardized mesh will land, but according to the SIG release, the Working Group expects to have the specification ready for prototype testing later in 2015, and the SIG will look to officially adopt profiles in 2016.

 

  • What Bluetooth solutions does CSRmesh run on?

CSRmesh is a protocol that was built with the aim to run on Bluetooth 4.0 and later. Bluetooth Smart is the only prerequisite necessary for CSRmesh to work, and you can run it on our existing generation of Bluetooth 4.0 devices. See our CSR101X product family here – http://www.csr.com/products/csr101x-product-family.

 

  • I would have thought Bluetooth Smart isn’t the most appropriate technology for meshing – aren’t there issues with range and power consumption?

CSRmesh by its very nature addresses these two issues. Bluetooth Smart was designed to be the lowest power radio on the market, and mesh networks were conceived to resolve the issue of range. Some have raised the point that there is a need to be wary of the power consumption of routing nodes, which will be listening and receiving most of the time. However, there is no routing in this mesh and therefore no setup time, no concept of router, coordinator or end device, no extra memory or processing overhead. All nodes are a simple low cost Bluetooth Smart SoC.

CSR recently announced CSRmesh Home Automation which will be available in Q2 2015. This will include sensor and actuator models that specifically address power consumption, response time and latency. Sensors will only wake up when they have data to send. The actuators wake up more frequently to be responsive but they can still sleep a long time. CSRmesh is a flood mesh, and in such a mesh there are more nodes around that are capable of repeating messages, therefore there is a higher chance that messages will get through to receiving nodes. The more nodes you have, the more you can turn the scan rate down.

CSRmesh is much more than just range extension. The intelligence in the network is distributed across all its members. Your lightbulb can proxy for heating sensor values so they can remain asleep most of the time. Your nodes can help you find your misplaced car keys by BLE RSSI. Your porch light comes on when you approach your front door at night by proximity – no other sensors are required. As an example Wireless Cables have developed the AirCable solution using CSRmesh. Their CEO, Juergen Kienhoefer, claims that with a very low ad rate and only about 10ms listen time, the battery impact is pretty low. His measurements are 35uAs for an ad package and about 150uAs for the mesh listener. Based on these measurements, an ad rate of 10 seconds would mean your standard battery could run for months or years.

 

  • How secure is CSRmesh?

I’ve covered the security aspects of CSRmesh in a separate blog post which you can read here.

 

  • Is it easy to integrate CSRmesh with wall control panels and remote controllers?

Yes – CSR partners like Avi-on are doing just that with their home automation solutions for solutions like wireless light switches.

 

TV remote controls are turning towards using Bluetooth Smart. Although cheaper, IR remotes are no longer useful for Smart TVs. Bluetooth Smart is a great replacement technology because it doesn’t need line of sight, it handles accelerometer and gyros for mouse pointer and motion for gaming and can even support just waving the remote to issue a direct command or even a CSRmesh command. All of this runs on same low cost SOC which also includes CSRmesh.

 

  • How does CSRmesh cope with multiple smartphones/remote controls operating simultaneously? Shouldn’t it be the gateway’s responsibility to handle these complex aspects?

There is no problem with supporting multiple controllers in CSRmesh. The TV remote, light switches and multiple smartphones all have unique addresses on the mesh. CSR even has ways to share the controlling device database to other controllers in a multi controller mesh without a gateway, although this can probably be best done in the cloud. Routing and IPv6 stack running on Bluetooth Smart is an unnecessary and heavy burden, which is why this isn’t enabled in CSRmesh. The whole idea being that the mesh works locally without the need for a gateway or internet connection (which has security benefits too), with no single point of failure if the Internet goes down. When you do need to control, configure and monitor remotely, then for the IP terminates at the gateway and CSRmesh takes over with its own lightweight addressing scheme more suited to Bluetooth Smart devices. Being a broadcast mesh (with flood control and acknowledgements) there is no routing to be done either, no setup time latency and no tables to maintain.

 

  • Is it possible to implement voice communications over mesh?

Bluetooth Smart can support voice commands. The SoCs that make up the CSR101X product family use hardware to process the lower levels of the Bluetooth radio stack. This means that the radio can switch on and off quicker than if it was done via software. There is also more link budget available (on average – 64kb/s) for accurate voice interpretation.  Bluetooth Smart is not designed to support voice communications and audio streaming – the bandwidth is just not high enough. However it is high enough to support short voice commands. See our CSR µEnergy® Remote Control Development kit for more information.

 

  • Is CSRmesh hampered by a lot of interference on the 2.4Ghz frequency?

CSRmesh is designed to coexist with Wi-Fi. It only takes a millisecond to send information on the mesh and this is sent on three separate channels (Channels 37, 38 and 39) which are out of range of the most common Wi-Fi router channels. We use all three channels so if one is blocked, there is a good chance the other two will get through. This step is repeated three times, so in effect each message is relayed nine times. This means there is very little chance that a concurrent Wi-Fi network will interfere with the workings of CSRmesh. This is unlike Zigbee and RF4CE networks which have a track record of being trodden on by Wi-Fi interference. The coexistence of Bluetooth and Wi-Fi has been proven by the long history of Bluetooth/Wi-Fi combo chips in smartphones.

 

  • How simple is it to set up a CSRmesh network?

It is incredibly simple. The key point here is that CSRmesh does not need a hub or access point to keep running. All you need to start is one CSRmesh Bluetooth Smart light bulb or switch or smart plug and a smartphone. Download the associated app and away you go – you can start talking to the devices immediately. Then simply add as many more as you wish and you can use the app to group them together as you wish – you will automatically be creating a mesh network for them to relay messages through. Talk to them individually, as a group or all together. There are no expensive hubs to buy or configure and no complex setup. The only time you need a hub is if you want to monitor or control your home when you are away from it, so with CSRmesh Home Automation in Q2 2015 we will be providing low cost Bluetooth Smart to Wi-Fi, IP bridge and gateway solutions for that purpose.

 

  • Is the power consumption low enough for batteries to be practical?

If a device is acting as an active mesh member, then it needs to spend some of its time listening for messages to relay. A device such as a light switch can be a passive mesh member, i.e. it only ever sends a command (when someone presses it) into the mesh and never listens for messages. In this case it is an originator device, not a recipient or a relay device and can live happily off a coin cell battery for several years, but it cannot relay messages for other nodes. For power connected lights, battery life would pose no problem.

In the Home Automation release of CSRmesh developers will have the added capability to tune the scan rate of the node so that it is partially sleepy and can therefore benefit from extended battery life. This feature takes advantage of the flood mesh nature of CSRmesh. By how much you can reduce the scan rate wholly depends upon a couple of things: (i) how many nodes you have around you to relay the message and (ii) how hard (long) the originator tries to send the message. We will issue some guidelines and applications support around this at the time of release.

 

  • What is the maximum network size CSRmesh can support?

The maximum theoretical size that CSRmesh can support is determined by the 16-bit device ID and 16-bit group ID. Therefore up to 64,000 devices can be supported and 64,000 groups per network key.

CSR Lights Up Las Vegas Nightlife with 1,000 CSRmesh™ Connected Glow Sticks

Although the conversations about Bluetooth® Smart at CES 2015 earlier this month centered around the connected home, the possibilities it provides go far beyond it. CSRmesh™ enables a single mobile device to control a nearly unlimited number of Bluetooth Smart enabled devices that are networked together.

At our Connected World exhibit at CES 2015, we demonstrated the role that CSRmesh™ will play in the Internet of Things experience of the future. But we wanted to go outside the home to ambitiously illustrate its potential, so CSR collaborated with our partner Incipio to create a truly unique and memorable experience for its CES party at Life nightclub in Las Vegas.

We created 1,000 CSRmesh™ connected glow sticks to hand out to the event’s attendees. Inside of each glow stick was a simple LED light connected to a CSR1012™ chip.

With a custom app, the DJ was given the power to control every attendee’s glow stick to, for example, change the colors on-the-fly or display patterns in rhythm to the music. Because CSRmesh™ enables any device to relay a message to any other, the DJ’s messages were instantly spread across the entire colossal venue without worrying about range restrictions. As long as one glow stick was in range of another, the information was communicated.

In the Internet of Things, lighting, music and mobile devices can now interact in new and innovative ways to enhance the entertainment experience. CSRmesh™ makes it all possible.

Watch the video below to see CSRmesh™ light up the party.

Keep track of your personal belongings with PebbleBee Bluetooth® Smart Tag

PebbleBee is a Bluetooth®-enabled tracking tag that uses the single-chip CSR1010™ to help its customers never lose their personal belongings again. Its Kickstarter campaign struck up over 3,000 backers contributing over $200,000 – ten times the original target – to help make the vision a reality. Founder and CEO David Daoura spoke to CSR to give his insight on how Bluetooth Smart is helping bring the PebbleBee to market.

What is it about the PebbleBee device that is so exciting?

People don’t want to lose things. On average you spend ten minutes a day looking for things you’ve misplaced, or 20 minutes for me! That’s lost time you’ll never get back. By placing a PebbleBee on your treasured items, you can quickly locate them and never lose anything. That’s the basic feature of the device.

Furthermore, by using the CSR1010 we can provide extra functionality for people such as remotely taking selfies with your phone, setting range alerts, keeping track of your items’ location history on Google maps, and much more. All that in an affordable, sleek and small functional device.

IMG_5035

When developing the PebbleBee what were the top things you wanted to achieve?

Firstly we wanted to create a quality, compact product with a sleek design that is durable. The main purpose of the device is for loss prevention and lost item recovery, meaning it needed multiple embedded sensors for monitoring the environment at an extended range. It also needed to have a replaceable battery with a long life.

Why did you choose to work with CSR?

We chose to work with CSR for a number of reasons including that the CSR1010 is the most widely used Bluetooth chip. CSR also has very responsive customer support and competitive pricing. We are also interested in the cutting edge technology produced by the CSR team, for example CSRmesh networking.

How do you think the market for smart trackers and sensors will evolve over the next five years?

It really depends on the battery and Bluetooth chip technology. Power management is what it all boils down to. The more power you can harness or conserve for a small device, the more user friendly it is. This translates to more people adopting and using this Internet of Sensors market. We aren’t just a manufacturer of tracker devices, we mainly focus on sensors. People want to know how active their pets are while they’re at work or who ripped that pillow apart at 3:00am. With sensors all of that information is available to you from the comfort of your mobile phone or tablet.

In the next five to seven years from now, I think the smart tracker market will be as big, if not bigger than the cell phone market is today. The devices will be so small that you can stick them on paper and won’t know the difference. High value assets in mail, items, toys and even merchandise and clothing will all have some sort of tracking device on them. Retailers will use them as they do today with RFID, but with Bluetooth Smart instead. The key is improved battery technology that is smaller, more efficient, and thin as a film and Bluetooth Smart chips and sensors that hardly consume any energy.

Internet of Things enabler CSRmesh™ named CES Innovation Awards Honoree

I’m pleased to announce that CSR has been named a 2015 CES Innovation Awards Honoree in recognition of our CSRmesh™ protocol.  Products entered in this prestigious program are judged by a panel of independent industriaInnovHon2015l designers, engineers and members of the trade media to honor outstanding design and engineering in cutting edge consumer electronics products. We believe CSRmesh will truly revolutionise development of not just consumer smart home products, but also smart buildings in general – even hotels and warehouses.

CSRmesh allows any device to send messages into a mesh network that other devices can receive. These devices need not be adjacent; instead, devices relay messages to increase coverage. Information in messages can action other related events: walk up to your front door and touch the handle to unlock it; the lights and heating turn on, the security system disables and the radio tunes into the channel you’ve just been listening to in the car. Allowing everything to be linked – but without requiring any central management or box – means that the occupier can build their smart home one device at a time. Each new device acquired makes their home smarte.

Our main objective with CSRmesh is to facilitate smart home automation without the hassles of existing systems: no vendor lock-in, no single point of failure, easy control from devices people already own and whole-building coverage. The innovation is in leveraging the ubiquity of Bluetooth – in phones, tablets and laptops – to control and monitor other devices. Using CSRmesh, we can exchange messages within a single room, or across a whole building. You can find out more about it here, as well as details of our CSRmesh Development Kit here.

Products chosen as CES Innovation Honorees reflect innovative design and engineering in some of the most cutting edge tech products and services coming to market. It’s clear that the panel value the benefits and unique features that CSRmesh can bring to the IoT – the creation of an industry-wide ecosystem of interoperable devices that can work together to make our lives easier.

CSRmesh will be displayed at CES from January 6-9, 2015 in Las Vegas. If you’re interested in a demo drop us an email at bluetoothsmart@csr.com

Secure smart lighting: CSRmesh™ leading the way for secure home automation

Many readers may have come across this story regarding a brand of connected LED light bulbs which can be hacked to change the lighting, and worse, to reveal the homeowner’s Wi-Fi® Internet password. It’s a serious issue, and it has illuminated (pardon the pun) that security needs to be considered in depth when Internet of Things (IoT) devices are being developed.

On this note, I thought it would be worth allaying any fears that CSRmesh™, our game-changing protocol which allows for Bluetooth® Smart mesh networks, could be subject to similar breaches. We have considered security at every stage of the design and as such, it primarily prevents against eavesdroppers, man-in-the-middle attacks and replay attacks, and is considered highly robust.

To illustrate this, let’s consider how you add a new device into a CSRmesh network. The network is secured using an encrypted network key. This is derived from a password or phrase that the user is asked to input when they first download the app onto their smartphone. To make the process of adding devices into the CSRmesh network easier, it is possible to publish a ShortText code, barcode, or QR code with the device. This code may contain the device address (128-bit UUID), the 64-bit authentication code, and other short information that may be relevant. This is particularly useful for deployment of larger networks.

During device association, the smartphone app will exchange keys with the advertising device and an encrypted network key will be provided to the device upon completion of the association process

During device association, the smartphone app will exchange keys with the advertising device and an encrypted network key will be provided to the device upon completion of the association process

Eavesdropping

The next phase is about trusting the new device. Once each device has its peer’s public key, then they can start to generate a secret authorisation value using a complex algorithmic process. To test this authorisation value, both the configuring and new devices share a public key and then challenge the peer device’s knowledge of this authorisation value such that they can be assured that not only has the public key been distributed correctly, but that the peer device knows the authorisation value.

Once they have authenticated each other, only then will they distribute the network key, using AES-128 encryption. This mea

ns that nobody else can eavesdrop on this communication to determine the network key. All future messages sent over the network will be encrypted using the network key and only trusted members of the mesh network will know that key and be able to decrypt these messages. Messages containing a different structure or network key, such as those from neighbouring networks, cannot be decoded and are simply ignored and dropped. It is therefore not possible to control or listen-in to a neighbouring network, nor to derive the network key from it.

Man-in-the-Middle Attacks

An optional authentication procedure can be employed using the private key to verify the validity of new devices before adding them to the network. A QR code or similar, containing this authentication code or private key, can be used for out-of-band authentication of devices appearing on the network and requesting access or association to the network. The smartphone, or associating device can scan the QR code from the device’s original packaging and thus securely obtain the authentication code “out-of-band”. When this device later appears on the network requesting association to the network and therefore requesting the network key, it can be challenged to also provide this out-of-band information or private key. This is then compared with what the associating device already gleaned from the QR code. If the two match, then the device is authenticated and the network key is encrypted and securely passed to the device being associated.

This authentication process therefore prevents an unknown device from accidentally or intentionally gaining access  to the network, a process known as a “man-in-the-middle” attack.

The relaying of messages through the mesh network is also securely managed. To accomplish this, each device that relays messages must also know the encrypted network key. Only messages that can be authenticated against a known network key are relayed. This allows devices that are near other mesh networks, for example a device near to a neighbour’s property, to only relay messages for known networks and not for any foreign network messages.

csrmeshloopReplay Attacks

There is always the potential for someone to steal the network key from a trusted network device, either by recording the encrypted information it is sending over the airwaves and playing it back at a later time, or by physically removing a device and reading its non-volatile memory. For this reason we prevent against ‘replay attacks’, someone trying to mimic a good network device message at a later time to try to gain access. A sequence number identifier is incremented and transmitted with each mesh message. If messages are replayed out of sequence then they are simply dropped and ignored. The network key data is not stored in a logical location in non-volatile memory, but is distributed across the memory hash table, making it very difficult to locate and identify. We would also recommend that any external trusted network devices use a separate network key that does not, for example, provide access to buildings or other secure areas.

The current release of CSRmesh for lighting supports only one network key per device, but a future version will support multiple network keys. This facilitates a ‘class of service’ structure for sub-networks within a building e.g. hotels which may require the enabling of different security zones.

 

Within the CSRmesh protocol there are also other security and control features such as:

  • Time-to-Live (TTL) counter: which determines how many hops or relays a message is allowed to make within the mesh network. The TTL is decremented every time a message is relayed. When it reaches zero, the message can no longer be relayed. This limits the size of a network and sets a boundary
  • TID message identifier: each message carries a unique TID. Devices receiving a new message compare its TID with the last few previously heard messages’ TIDs. If they are the same, that message is dropped,  meaning that messages that have already been heard before are not repeated again. This limits the proliferation of messages and prevents echoes and infinite loops in the network
  • A Seq sequence number: this maintains the location of messages within network and time. If messages appear out of sequence they are ignored, preventing record and replay attacks upon the network

 

As you can see, security is not something that is simple. Nor is it something that should be an afterthought in terms of design. It must be integral to the design of both the architecture and implementation of a networking solution. CSRmesh has been designed from the ground up to be as difficult as possible to be compromised, but it still includes the flexibility to increase the level of security over time as security algorithms improve.

Qardio makes health monitoring easy with CSR1010™ Bluetooth® Smart

With connected medical devices one of the most exciting aspects of the growing Internet of Things, we caught up with Qardio, a company in the business of making smart wearable heart health monitors. Rosario Iannella, Chief Technology Officer at Qardio, discusses the benefits CSR’s Bluetooth® Smart technology brings to the company’s latest device, the QardioArm, and his thoughts for how the smart medical devices market will evolve.

CSR: You recently launched the QardioArm blood pressure monitor, which uses the CSR1010™. What’s exciting about the device?

Qardio: QardioArm is a blood pressure monitor with a revolutionary design and effortless user experience that conveniently fits the modern lifestyle. The idea behind the product was to create a medical device that looks like an everyday object and is simple and convenient to have around at all times for daily measurements.

"We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points." - Rosario Iannella, CTO, Qardio

“We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points.” – Rosario Iannella, CTO, Qardio

CSR: When developing the QardioArm what were the top five things you wanted to achieve? 

Qardio: We wanted QardioArm to be easy to use, comfortable, clinically validated with safe data transfer and to have a long battery life. All of this has been possible with the use of CSR’s Bluetooth Smart technology.

The ability to control the device pairing experience directly from the smartphone application has ensured the device is incredibly simple to use from the very first time. A simple tap between the QardioArm and the phone and the user is ready to start using the product.

We wanted the device to be comfortable and the combination of the wireless technology with the compact design created a blood pressure device that is simple and convenient to have around at all times for daily measurements.

The low power consumption offered by CSR’s Bluetooth Smart technology means users don’t have to continually charge their device. And the small form factor of the chip has helped us deliver a compact design.

Users want to feel confident that data is accurate and safely stored. The encryption mechanism embedded in Bluetooth Smart technology has been crucial in helping us achieve that.

CSR: Why did you choose to work with CSR?

Qardio: We looked at different parameters like throughput, power consumption, module design and the completeness of the Bluetooth stack feature set. CSR performed better on every one of these points.

CSR: How do you think the personal medical market will evolve in the next five years?

Qardio: The market has seen an explosion of self-quantified applications in the last few years. Now with medical devices coming to the market with a consumer-focused design we will start collecting an unprecedented amount of clinical data that will help improve patient care. We will see companies creating predictive algorithms giving people the ability to truly achieve preventive care, lowering the unsustainable current trend of increasing healthcare costs.

 

The QardioArm records blood pressure readings and uploads them to the cloud, which can then be accessed via an iOS app

CSRmesh™ – A key component to the Internet of Things and the world’s most exciting technology, says The Times Raconteur special report

CSR was featured this week in the ‘Internet of Things’ special report, published by the prestigious Raconteur and distributed in The Times. It contains an interesting series of articles looking at how everything is getting plugged into the internet and how through machine-to-machine communications, it is making a sizeable impact on how we live. It’s worth a read, but definitely check out pages 8-9, where CSRmesh is not only mentioned as one of the ten applications making the IoT the world’s most exciting technology, but also because it features a great infographic exploring the segmentation of the IoT market.

“Devices in close proximity relay messages to each other to form a local network. For example, Cambridge Silicon Radio’s CSRmesh uses the Bluetooth radio signal found on every smartphone. The consumer connects to a Bluetooth-smart IoT device, which then sends that message to affiliated devices in a giant chain or mesh. Bluetooth can stretch 30 metres, but via a mesh, a message can leapfrog devices to cover much larger distances.”

Sky News reports on CSRmesh™ and Bluetooth® powering the Internet of Things

CSR recently met with the SWIPE tech team from Sky News to talk about how Bluetooth® is changing the way we interact with the world. Reporting from the Future is Smart exhibition organised by the Bluetooth Special Interest Group, the report focuses on CSRmesh™ having a key role in the future of wireless technology:

“Bluetooth isn’t just about mobile headsets anymore, a new generation of wireless technology is ready to transform homes, exercise, medicine and even farming. It’s because Bluetooth 4.0 lets devices talk to each other using very little power, like these light bulbs from Cambridge-based company CSR. One app can control tens of thousands of [light bulbs] at once, right down to changing the colour of each individual bulb. And the technology has even greater potential.”
